Abstract

In this research, the effect of Ni loading on the structural and catalytic properties of the Ni/10%Sr-Al2O3 catalyst prepared by the wet impregnation method was studied in Dry reforming of methane. The samples were characterized by X-Ray Diffraction (XRD), N2 adsorption, temperature-programmed reduction and oxidation (TPR, TPO), and scanning electron microscopy (SEM) techniques. The XRD results revealed that increasing Ni loading increased the NiO particle size. The BET results showed that the catalysts possessed a mesoporous structure and 5%Ni/10%Sr-Al2O3 catalyst exhibited higher surface area and CH4 and CO2 conversions compared to the other catalysts. It was found that the raise in Ni loading from 5 to 15 wt. %, increased the amount of deposited carbon which was in agreement with the results of SEM analysis. In addition, the long term stability of the 5%Ni/10%Sr-Al2O3 catalyst showed High stability during 13 h on stream at 650 oC.
